While searching it seems that maybe one person has used the 90080-19023.

These are the ones that are too long and need two rings to be ground off to even fit down the hole.

It's my probably wrong impression that all of the COPS listed in the faq trigger on the falling edge. Bench testing the 90080-19023, it fired on the rising edge.

The question is if these are 100% compatible with the other p/n's.
